I could see two options to troubleshoot this problem
One Option is Create External Table for this S3 Json File and build View on top of it to view the Json data , check possible null values coming from Json key-value pair elements
If you think your JSON File is heavy and viewing data out of External Table using View is not giving the expected query performance to troubleshoot this issue then Second Option is to load this file into your internal stage and then build view on top of it to analyze your null key value pair elements.
